The invention is applied to a filled bag sewing machine of the typewherein the filled bag is placed on a carriage capable of traveling backand forth on tracks. These tracks are mounted on a supporting frame sothat they may be adjusted vertically. The sewing head is alsomounted onthe same supporting frame so as to overhang the traveling carriage andsaid sewing head is also capable of being adjusted vertically. The samebracket which supports the sewing head also supports the motor fordriving the sewing head. A vertical screw shaft is provided foradjusting the sewing head vertically on the frame and Means is providedwhereby the screw shafts may be independently rotated or simultaneouslyrotated. This enables the, sewing head and the traveling carriage to bequickly moved toward or from a given point simultaneously or theoperator may movethe sewing head independently of 'the supportingcarriage and, again, the operator may move the supporting carriageindependently of the sewing head. This enables the machine to be readilyadapted for operating upon bags of various'sizes and at the same timemaintain the stitching level so that it wi-llbe very convenient to theoperator.

As noted above, the sewing head and the operating motor are shiftabletogether vertically. The stitching mechanism is controlled by a leverwhich is also mounted to move bodily with the sewing head. The distanceof this lever from the floor will, therefore, vary as the sewing head isshifted. A treadle is mounted on t-he supporting base of the machine,whereby the sewing head is controlled and in orderto take care of thevary ing heights to which the sewing head may be placed, automatic meanshas been provided forming a part of the controlling means whichautomaticallycompensates for the different heightsto which the sewinghead may beset. This compensating means consists broadly of 'a rotatablepart having a flexible connectionwith theicontrolling lever of thesewing head. A weight is also attached to this rotatable part by aflexible supporting means. and the weight normally tends to rotate thepart so as to wind up the flexible connection extending to thecontrolling lever of the sewing head. This weight when the rotatablemember is free will take all the slack out of the flexible connection tothe controlling lever. A treadle is connected to an operating leverwhich when depressed will clutch up with the rotatable part andpositively turn the rotatable part so as to actuate the controllinglover.

The invention will possibly be better understood by a more detaildescription of the apparatus shown in'the drawings which illustrate oneembodiment of the invention.

In the drawings, the machine is shown as consisting of a supporting base1, centrally of which is a vertical column 2. This vertical column maybe formed of a hollow cy- V lindrical pipe which is of sutficientstrength to supportthe parts and yet not of excessive weight. Extendingout from the support ing base 1 are four substantially horizontallydisposed legs 3, each ofwhich is provided with a castor or supportingroller 4 which is connected to the leg so that said castor or roller mayreadily turn to'accommodate the direction in which the apparatus is tobe moved. Extending from two of the legsare bolts 5 which may beadjusted vertically and secured in adjusted position by means of a locknut 6. These bolts may be used to level the machine and securely holdthe machine from movement when it is brought to a desired position foruse. The legs 3 are made of angle iron and these angle iron sections arebolted to the supporting base 1. Brace rods 7 are also bolted to thevertical portions of the angle irons forming the legs and this makes upa skeleton supporting portion for the apparatus which is strong anddurable; also which is light and which can be very cheaply made.

At the upper end of the column 2 there is an adjustable bracket 8. Saidbracket is formed in part by a sleeve 9 which slides freely on thecolumn 2. Said sleeve has formed integral therewith a forwardlyproject-ing support 10. The sewing head is indicated at 11. Said sewinghead is bolted to a plate '12 formed as a part of the support 10. Thesewing head is of the usual construction. Said sewing head has a needlebar 13 carrying a needle 1% and the needle bar is reciprocated by meansof a needle lever 15, which needle lever is in turn oscillated by aneccentric strap 16, co-operating with an eccentric-on the main shaft 17.The machine also includes a suitable presser foot 18, and feed dog 19which is actuated in the usual manner from the main shaft forintermittently feeding the mouth of the bag step by step to thestitching mechanism as it is stitched. There is also mounted in thecylindrical arm 20, "besides the feeding mechanism, complement-a1 stitchforming mechanism which 'co-operates with the needle in forming thestitches. This sewing head may be of any desired construction andfurther description thereof is not thought necessary.

Also, extending laterally from the sleeve 9 is a second supportingmember 21. This supportingv member 21 is on the opposite side-of thesleeve from the supporting member 10. A motor 22 for operating thesewing head is secured to a plate 23 which is bolted by means of bolts24 to the support 21. The motor is secured to this plate 23 by bolts 2525. It will be noted that the motor is on the oppositeside ofthe columnfrom the sewing head and therefore in a sense counter-balances thetendency of the weight of the sewing head to cause the sleeve to bind onthe column so that the sleeve will more smoothly move up and down on thecolumn. The plate 23 may be adapted to different sizes and s his ofmotors.

Also extending out from the sleeve 9 is a support 26 in which is mounteda'transmitter for transmitting power from the motor to the sewing head.Thiszsu'pport 26 consists of an upper arm 26 and a lower arm 26.Journale-d in these arms is a shaft 27. Mounted on the upper end of'thesaid shaft 27 is a groove pulley 28. The groove pulley '28 is adapted tobe belted by means of a belt 29 to a belt wheel 30, on the main shaft 17of the sewing head. Also fixed to theshaft 27 is a combined clutch andbrake disk 31. On the under face of said disk 31 there is a flexiblefacing 32 which is adapted to be engaged by means of a belt wheel 33which is free on the shaft and capable of endwise movement on the shaft.This belt wheel 33 is connected by means of a belt 34 to a belt wheel 35on the motor shaft so that when the motor is running the belt wheel 33is continuously operated. A spring 36 normally presses the belt wheel 33away from the facing 32 of the disk 31, so that these parts aredisengaged and while disengaged the loose belt wheel willrun freelywithout in any way turning the shaft 27. g As a means for bringing theloose belt wheel into driving contact with the disk 31, a controllinglever 37 has been provided. This controlling lever 37 is pivotallysupported by the bracket 8 so as to swingin a vertical plane and saidlever carries a forked arm 38 which straddles the shaft 27 and. isadapted to move the belt wheel 33 endwise on the shaft. A ball bearing39 is locatedbetween the end of the forked arm 38 and the belt wheel 33.There is also a ball bearing 40 between the disk 31 and the upperbracket arm 26. This controlling leverat its free end is connected to aflexible member 41 which is capable of being depressed by means of atreadle which will be described later, and when depressed the belt wheel33 makes con.- tact with the disk .31, rotates the shaft 27 and this inturnrotates the main shaft of the sewing head. lVhen the flexible member.41.

is released then thecontrolling lever is moved by means of a spring soas to lower the forked,

a which in turn bears against the belt wheel 33.

Of course, gravity also tends to move the belt wheel 33 downwardly outof engagement with the disk 31.

The shaft 27 is a hollow shaft and is provided with a suitable oilsupplying means, indicated at 43. The controlling lever 37is providedwith an upper arm 44, which is moved forward into contact with'thecylindrical surface of the disk 31 when said con trolling lever is swungto release the belt wheel 33. This arm 44 serves as a brake to stop therotation of the transmitter and thus 7 stop the rotation of the sewingmechanism.

Also extending laterally from the sleeve 9 is an arm 45 in which isfixedly mounted a nut 46 adapted to engage a threaded shaft 47. As thisthreaded shaft is rotated the nut 46 will be caused to travel one way.or the other on the shaft for the reason that the shaft is mounted insuitable bearings which prevent any endwise movement thereof- Said shaft47 at its upper end is mounted in a bearing carried by a laterallyprojecting arm48 secured t0 the upper end of the column. The shaft isprovided with a reduced section 49 at its lower end which is mounted ina bracket 50 secured to the column intermediate its but any rotationimparted to the beveled gear will rotate the shaft. Extending laterallyfrom the bracket 50 is a supporting arm 53, provided with a sleevebearing in which is journaled a shaft 55. Rigidly secured to the outerend of the shaft is a hand wheel 56 carrying a hand crank 57. Thisenables the shaft 55 to be rotated by hand. the shaft 55 is a beveledgear 58 which is so positioned that the beveled gear 52 may meshtherewith when at one position on the shaft 47. There is a spring 59between the beveled gear 52 and the bracket 50 which normally forces thegear 52 upwardly on the shaft 47 to which it is splined and to a pointwhere the teeth of the beveled gear 52 are out of mesh with the teeth ofthe beveled gear 58. Directly above the beveled gear 52 is a collar 60which is provided with a radially projecting pin 61 which enables thecollar to be freely turned. This collar is provided with a cam groove 62(see Fig. 2). Fixed to the shaft 47 is a pin 63. \Vhen the collar is inthe position shown in Fig. 6, this pin rides on the outer face'of thecollar and will cause the collar to force the beveled gear 52 downwardlycompressing the spring 59 and bringing said beveled gear into mesh with,the beveled gear 58 on the shaft 55. When,'however, this collar 60 isturned so that the pin 63 may move into the cam groove 62 then thecollar will slide endwise on the shaft and permit the spring to forcethe beveled gear 52 out ofmesh with the gear 58.

When the two gears above described are in mesh, then the sewing headmaybe raised andlowered by the turning of the shaft 55 through the aidof the hand wheel. If, however, these gearsare out of mesh the turningof the hand wheel will notturn the shaft 47 and therefore said handwheel maybeturned without imparting any movements up an d down to thesewing head. hen the gear 52 is out of engagement with the gear 58 thesewing head The filled bag which is to be closed is placed Fixed to a ona carriage-64. Thiscarr-iagefiat is mounted so as to be moved onsupporting tracks (dB-65. The tracks 65 are in turn mounted on arms6666, which arms are bolted to the opposite ends of a bracket 67, whichbracket at the central portion thereof is provider with a sleeve 68which is adapted to engage and freely slide vertically on the column 2.The bracket extends outwardly and downwardly from the sleeve-and carriesat its outer ends the arms 66, as above noted. The arms 66 are formed ofangle irons and the tracks 65-65 are formed of the usual well-knownU-bars or channel bars. These tracks are spaced the proper distanceapart to receive the carriage. The carriage is provided "with dependingspaced brackets '69 arranged at each end thereof, and in these'spacedbrackets is a supporting shaft 70, and at each end of the shaft is aroller 71 mounted on ball hearings and these rollers are in the form offlanged wheels, as clearly shown in the drawings. The flanged wheelssupportingthecarriage run on the lower members of the U-ba rs formingthe tracks 65-65so that theseU-bars serve as a housing for the avheels.This is quite an important feature for the reason that these filled bagsare used in mills where there is a great deal of dust and dirt and thetrack serves as a housing for the wheels and thus in a measure protectsthe same from thedust and dirt. The tracks 65 65 are arrangedsubstantially horizontally.

The bag to be stitched is placed on the 'carriage and the carriage ismoved by the feed of the machine as the bag is being stitched and thusthe bag is kept substantially vertical as it moves beneath thesewingfhea'd. *It will be noted from Fig. 3 that the supporting plate ofthe carriage is slightly :"narrow at its forward end soas notto overlapthe track 65. At the extreme left-hand end of the tracks there is aLl-shaped rod -72 which is rigidly secured to the tracks. The ends ofthe rods extend down through the channel bars and are threaded. Nuts 73and '74 above and below the channel bars rigidly and adjusualbly supportthe same. The forward-end of the carriage passes between the verticalportion of the U-shaped rod 72 and causes the bag mounted on thecarriage to engage said rods. 1 Said rod will be adjusted so as toengagethe bag at a point below its center of weight and as a result the bagwill tilt forward over the rod and off from the :carriage. As the bagtilts oil from the carriage, by this engagement with the rod and swinginover the rod, the bottom of the bag will give the carriage a backwardkick and this will cause the carriage to :run back to the other end ofthe track.

As a means for holding the carriage at the right-hand end of the tracksuntil it is desired to move the same forward with a L- 1 .v h red bagthereon, a stop mechanism has been provided'consis'tingof a lever 7 5.Said .lever 75 isip'ivotally supported by a bracket 7 6 at the rear endof the lever and the forward end=of:the lever is capable of moving upand down in a second member 77 ri idly secured to the carriage. A spring7 8 mounted in the member 77 bears against the under surface of the"lever 75 and normally tends to raise the same. The lever is providedith an upwardly projecting portion 7 9 which is adapted to move upthrough a slot in the supporting plate of the carriage. It will readilybe seen that when a filled bag is placed on the carriage it will engagethis portion "79 of the leverand force it down; and, on the other hand,when the bag is removed from the carriage the spring 78 will raise "thelever.

The upper member of the U-bars is provided with a notch 80 and thisnotch is so positioned that when the carriage is at theextreme'right-hand cnd-of the tracks, as viewed in Fig. 7-, the leverwill move up into the notch and hold the carriage in this position.Therefore, when'the bag falls off the carriage and the carriage is givena kick backward, it will irun'to the other end of the track and the stoplever will be moved up into the notch not only stopping the carriage butholding it in this position ready to receive the next filled bagand'until the filled bag is placed thereon.

The carriage is raised and lowered vertica'lly to accommodate differentsizes of bags bymeains of a threaded shaft 81. This shaft 7 81isimoun'ted in a step-bearingfBQ at the lower end thereof and isprovided with a reduced portion "83 at its upper end which is mounted inthe bracketSO. nected with the sleeve68 and this nut engages thethreaded shatter lVhen the threaded shaft '81 i's turned the nut willtravel endwise onithe shaft and thus raise or lower the-trackssupporting the carriagedepending upon in which direction the shaft isrotated.

At the upper end of the shaft 81 there is a beveled gear '85 which isadapted to mesh with the gear, 58 when it is in the position shown inFig. 6. This gear is normally forced in a downward direction on theshaft by a spring 86. The gear 85 is splined to the shaft andris'fre'eto move endwisethereof. A collar 87 mounted on the shaft limits thedownward movement of the gear 85. A pin 88 011 the shaft is adapted toCo-operate with the cam groove 89 in the collar 87. A pin 90 is fixed tothe collar 87 "and serves as a means for rotating the collar. It willreadily be-seen that when the collar is in the position shown in Fig.6,then the beveled gear 85 will beheld in mesh with the beveled gear 58.hen, however,the collar-87 is turned to the posit-ion shown in Fig. 2,then the beveled gear85 'is forced out OI mesh with the beveled gear 58.hen the beveled gear 85 is out ofmesh withthe beveled gear58then thehandA not 84 is rigidly concarried shaft may be turned without rotating thethreaded shaft 81 and the threadedshaft 81 will support the tracks inthe position to which they have been adjusted by reason of the factwithout moving the carriage, and, again,

the carriage may be adjusted without moving the sewing head. When thesewing head and carriage are simultaneously adjusted they will besimultaneously movedtoward each other or from each other by reason ofthe fact that the shafts 17 and 81 when both in mesh with the gear 58will be rotated in opposite directions.

/ The flexible member 41 which is connected with the controlling leverfor the sewing head is connected atits lower end to a rotatable member91. Said rotatable member is provided with two spaced grooves 92 and 93and the outer sidewalls of the grooves are chamfered or beveledoutwardly away from the grooves. The flexible member ll which is eitherin the form of a chain or cord is wound about the central portion of therotatable member 91 in the groove 92 and is secured thereto. A secondfiexiblemember, such as a chain or cord 94, is located in the groove 93and is likewise Wound about the rotatable member and secured theretoThis cord 94 carries a weight 95 at its lower end. The'cord 9 1 is sowoundon the rotatable member as to tend to rotate said member in adirection to wind up the cord 41. This rotatable member 91 is freelymounted on a short shaft 96 and is held thereon by a threaded nut 97.This shaft 96 is in the form of a stub-shaft threaded into the bracket50. Mounted on this stub shaft and freely turning thereon isa lever'98.Said lever 98 is connected by means of a flexible connection such as achain or cord 99, with an arm 100. This arm 100 is rigidly secured to ashaft 101 journaled in suitable bearings by the supporting base and atits forward end said shaft 101 carries a secondarm 102 provided with afoot treadle 103,through which the shaft 101may be oscillated and thusimpart an oscillation to the lever 98.' Said lever 98 on one facethereof, is provided with beveled teeth 104 which are adapted tocooperate with beveled teeth 105 formed integral wither rigidly securedto the rotatable member 91.

which has formed therein a recess 10? with one wall thereof tapered.:The lever 98 has a tapered dog 108 which is adapted to co-operate witha tapered wall in the recessi107; As viewed in Fig. 3, it will be notedthat when the lever 98 is depressed this tapered dog moving out of therecess will move the lever laterally until the beveled teeth thereon'en-- Fixed on the shaft 96 is a collar 106 gage with the beveled teethon the rotatable member 91. This positively connects the lever with therotatable member so that any further depressing of the lever will turnthe rotatable member. When the lever is released, it is moved in anopposite direction by means of a spring 109 which also causes thebeveled teeth to move out of engagement with the beveled teeth in therotatable member 91, so that the lever is normally out of engagementwith this rotatable member.

WVhen the sewing head is raised the cord 41 willturn the rotatablemember, lifting the weight 95, and, therefore, the weight willalwayshold the cord 41 taut. 'If the sewing head is lowered which wouldtend to give slack to the cord 41, the weight will rotate the member 91and wind up the slack and again maintain the cord41 taut so that whatiever may be the position of the sewing head this weight and rotatablemember will compensate for said position. That is, it will automaticallytake up the cord 41 and all slack out of the same. depressed, therefore,and the lever is connected up with the rotatable part it will move saidrotatable part in such direction as to further wind up the cord Handoscillate the controlling leverwhich will start the sewing mechanism.

From the above, it will be apparent that therehas been provided a filledbag sewing When the treadle is! mechanism very light in construction andwhich can be very cheaply made. Said filled bag sewing mechanism alsoincludes a carriage which may carry the weight of the bag to be'closedand which carriage can be moved by the operator to feed the bag to thesewing head. When the carriage reaches the end of its travel, the bagengages the rod and falling" over the rod kicks the carriage in ther'eversedirection so that it returns to normal position for lacing thebag thereon. After the bag has een placed, the operator depresses thetreadle and starts the sewing mechanism. When the sewing is finished andthe treadle is released thesewing mechanism willbe disconnected from itsoperating motor and the brake applied to stop the sewing mechanism.

' The machine is readily adapted for stitching bags of varying sizes. Anoperator can much more readily feed the mouth of the filled bag to astitching mechanism if said iio sired range for shifting thesewing'machine. By the apparatus described above, it will readily benoted that the carriage may be raised when the head is lowered andtherefore, the apparatus is capable of being adjusted for a wide rangein heights of bags without excessive adjustment of the sewing head.Then,.again, it is often desirable to adjust. the carriage alone withoutadjusting the height of the head, so that the head may be left at adesired height for stitching and all adjustments made by raising orlowering thecarriage; There are also other condi-' tions under which itis desirable to raise or lower the head without moving the carriage upand down; as, for example, in the stitching of a bag where there is aworn place in the mouth of thebag, which makes it essential to stitchthat particular bag at a lower level. It will readily be seen that alladj ustmentsmay be quickly accomplished by the above apparatus. All theoperator has to do is to quickly throw the collars controlling thebeveled gears and the machine may be set so as to simultaneously raiseand lower the carriage and the sewing head or to raise the carriagewithout shifting the sewing head or to raise and lower the head withoutshifting the carriage. -In whatever position the sewing head maybeshifted the controlling mechanism operated by the treadle adapts itselffor the new position ofthe sewing head.

It is obvious that minor changes in the details of construction andthe'arrangement of the parts may be made without departing from thespirit of the invention as set, forth inthe appended claims. 1 7
